The density of ice is 0.9 kg / m3. When a certain amount of water solidifies into ice, its volume increases by 40 cubic centimeters. What is the mass of water?

The density of water is one kilogram per cubic meter
M water = 1 * V water = 0.9 * V ice
That is, V ice = V water / 0.9
According to the title, V ice-v water = V water / 0.9-v water = 40 cubic centimeter = 4.0 * 10 ^ - 5 cubic meter
The water yield is 3.6 * 10 ^ - 4 cubic meters
Water mass = 1 * 3.6 * 10 ^ - 4 = 3.6 * 10 ^ - 4kg

1. The density of water is --- 5 cubic decimeters; when water solidifies into ice, its volume will be --- mass --- 9
Use different materials to make two solid balls a and B of the same volume. Put two A's on Libra's plate and three B's on the right plate to balance the density ratio and mass ratio of a and B

The density of water is 1kg / cubic decimeter,
The mass of 5 cubic decimeter water is: mwater = 1kg / cubic decimeter × 5 cubic decimeter = 5kg
After water solidifies into ice, its mass remains the same: m water = m ice = 5 kg (the mass will not change with the change of state)
After water solidifies into ice, its volume is v ice = m ice / ρ ice = 5 kg / (0.9 kg / cubic decimeter) ≈ 5.6 cubic decimeter
V ice > V water, so when water solidifies into ice, its volume will increase and its mass will not change

1.8 m3 of water solidifies into ice (0.9 * 1000 kg / m3). What is its volume and mass?

1.8 × 1000 △ 900 = 2 M3
8 × 1000 = 1800 kg

What is the volume and mass of 1.8 cubic meters of water solidified into ice (0.9 times 103kg / cubic meter)?

The volume of water multiplied by the density of water is the mass, because when water becomes ice, the mass of water remains the same, so the mass of water is the mass of ice. Dividing the mass of ice by the density of ice is the volume of ice!

A 1m ^ 3 piece of ice melts into water with a mass of () kg and a volume of () m3?

Density of ice = 0.9 × 10 ^ 3kg / m3, density of water = 1 × 10 ^ 3kg / m3
After hydration, the mass is 1 × 10 ^ 3 × 1 = 1000 kg
Volume = 1000 / 0.9 × 10 ^ 3 = 10 / 9 M3

What is the ratio of the volume of a certain mass of ice to the volume of water it completely melts into______ ．

∵ the mass of ice remains unchanged after it is completely melted into water; ∵ according to v = m ρ, we can get: V ice, V water = ρ water, ρ ice = 1.0 × 103kg / m30.9 × 103kg / m3 = 109

It is known that the density of water is 1 and the density of ice is 0.9. Now the volume growth rate of a unit volume of water formed into ice is p, and the volume decline rate of a unit volume of ice dissolved into water is Q, then the relationship between P and Q is ()
A. P & gt; QB. P = QC. P & lt; QD. Not sure

If the mass is a. then p = V ice − V water, V water = a △ 0.9 − a △ 1a △ 1 = 19, q = V ice − V water, V ice = a △ 0.9 − a △ 1a △ 0.9 = 110, then P & gt; Q

The density of ice is 0.9 × 103kg / m3. When a piece of ice with a volume of 100 & nbsp; cm3 melts into water, the mass of ice is 0.9 × 103kg / m3______ g. The volume is______ When cm3.135 & nbsp; g water forms ice, its mass is______ Kg, the volume is______ cm3．

The density of ice is 0.9 × 103kg / m3. The volume of a piece is 100cm3, and the mass of ice is m = ρ v = 0.9g/cm3 × 100 & nbsp; Cm3 = 90g. Mass is the basic attribute of an object, which has nothing to do with the shape, state and spatial position of the object, so the mass remains the same after the ice melts into water, which is still 90g. After the ice melts into water, the density becomes 1.0g/cm3, so the volume of water is: v = m ρ = 90g1.0g/cm3 = 90cm3. Mass is the basic attribute of the object, which has nothing to do with the state change of the object, so water forms The mass after ice remains unchanged, which is still 135g, that is, the volume of 0.135kg.135 & nbsp; g water after ice formation is: v = 135g0.9g/cm3 = 150cm3, so the answer to this question is: 90; 90; 0.135; 150

The density of ice is 0.9g/cm ^ 3. What's the volume of a 1m ^ 3 ice melting into water? What's the volume of a 1.8m ^ 3 water solidifying into water

The volume of a 1m ^ 3 piece of ice after melting into water = 1 * 0.9 * 10 ^ 3 / 1 * 10 ^ 3 = 0.9 m ^ 3
A piece of 1.8m ^ 3 water solidified into water volume = 1 * 10 ^ 3 * 1.8 / 0.9 * 10 ^ 3 = 2 m ^ 3

After 0.9kg water condenses into water, the volume increases by 0.1dm cubic, so what is the density of ice?

ρ water = 1kg / DM ~ 3
V ice = V water + 0.1dm ~ 3
=M water / ρ water + 0.1dm ~ 3 = 0.9 / 1dm ~ 3 + 0.1dm ~ 3 = 1dm ~ 3
ρ ice = m ice / V ice = 0.9kg/1dm ~ 3 = 0.9kg/dm ~ 3
9 kg / DM ~ 3
Note: it is a semicolon or division sign
~3 means cubic
